simultaneously, or eitherside maybe used separately. V i I Folders are usually arranged with their deliveries placed one on each side of the inachine, butin some instances, it is necessary to place one side of. the pressquite close to a wall, and in such cases, there is insufiicient working space for removing the printed papers from the rear delivery;

Arrangements have been used in which both deliveries were located at one, sideof the machineas disclosed in Schmidt Patent No. 1,494,378 which shows an arrangement of conveyors which deliver the product of two folders at one side of the machine, and the two productsare carried closely adjacent to each other. In many cases it is preferable to keep the deliveries separated so that should anything happen tointerfere with the operation of either deliveryand cause a choke, the

operation of the other one will not be affected.

Other arrangements for bringing both deliveries to the front side of: the machinehave been used in which the delivery coming from V the rear of the machine was arranged on a descending inclineso that it might pass under the front delivery and still allow sufliclent space between them to give the"requ1s'1t e accessibility. Some difficulty was exper enced with this arrangement however, for lt was found that the papers would slip forward while they were on the inclined section of the delivery belts. i a

described herein,athe cutting and collecting cylinders,-and the delivery fan wheels are arranged instaggeredrelation, with the rear group at alower level than the front group, and the delivery from the rear group iscarried'onwa-substantially level plane, directly to the front of the machine, -"The use of adownward1y;.inclined' delivery is thus avoided, thereis-no liability belts. I ,-V i g The object of the invention is to providean I of a choke on either of the deliveries interf V I-fering with the operation of the other.

livery, and there is .ample'spacefor access to the papers whilethey are on the delivery arrangement foradouble. folder .whereinboth deliveries have theirbelts runningonasubstantially horizontal plane to the frontjside of the machine and"separated. from each ot'he'r so thatothe printed products on the delivery belts are, accessible.

It is also an object of the invention 6 151 6;

vide a double folder with front deliveries, that is of. generally improved construction,

whereby the device is simple, in construction,

as well as convenient, practical, serviceable and eificlent in its use.

With the foregoing and other view, which will appear as the description proceeds, the invention resides in, the combination and arrangement of parts, and in the V details of construct on herein-after 'described changes in the precise embodiment of the in vention herein disclosed may be niadelwithtion is'illustratedin the accompanying drawand claimed, it being understood that various The preferred embodiment of the inveni V. ng which shows an outline view o'f-a double folder, as's eenwhen looking" at the folder end of; the printinglmachinel A machine equipped? with this folder is adapted; for mounting with one side close to a wallor other obstruction, asthe products from both cutting mechanisms are brought to one'sideof the press, which is herein referred to, as the front side. 7 V i .7

The base frame of the machine is indicated by the, numeral 11, the front side frame by 12,

the rear-side frame by 13 and across frame by, .the numeral 14 Formers of the usual type are shown partly broken away at 15 and 15. The cutting cylindersare indicatedat 1G and '16 and cooperate respectively-with folding cylinders 17 and 17 which,-in accordance with the usual practise may fold either a collected or an uncollected product which "is passed: between the folding rollers- 18 and 19 or 18 and 19'. The folded papers then 'pass to fan wheels 21 or 21 and are delivered to the delivery belts 22 or22. Means for driving the folder may consist of a shaft indicated at 23 which is connected byv mitre .gears 24-. and25 to the vertical shaft'26 that v is supported in suitable bearings in brackets 27 secured to the frame 13. The bevel gear 28 meshes with the bevel gear 29 on the. shaft 31' that is rotatably,supported in brackets 32, 33 and '34 secured respectively to frames 13,14 and 12, and bevelygears35 and 35 mesh with mating gears connected respectively with the cylinders17 and I7 v, It will be; understood that in accordance with the usualflpractise, suitable gearing is provided toconnect the folding cylinders 17 andg17' with their cutting cylinders 16'and 16sothey are driven in proper timedrelation. "Similarly, infaccordance with the usual practise which is well known" to those versed in the art, the fan wheels 21 and 21 are driven by suitable gearing from the cylinders 1 6 and'l6", and the delivery belts 22 a'nd22 are'drivenlthroughbevel gears on the shafts 36'and 36 respectively, which carry worm wheels meshing with worms 'on the sha-ftsof the wheels 21 and 21. 'j,

The delivery belts 22' pass around pulleys on the shaft 37 and other pulleys38 support ed the arms 39, that inturn are supported V on a rod 41, secured to the frame delivery belts42, are arranged to convey the papers to a remote point. Likewise, delivery belts 22 pass around pulleys on the shaft 8? over an idler pulley L3, and around pulleys 44. Delivery belts 45, pass around pulleys j 44: and46, and delivery belts 42 extend from ver the former15, whereitreceives its first pulleysedtoa remote point." I 1 v A printed Web or group ofgwebs is; led

, fold, and it is'then passed to the cuttingcyL 'inders where it is :cut intosheets that are folded by the cylinde'rl? and passed between the foldingofl' rollers18 and 19, where they receive the second fold.'j The products then pass on to the fan wheel 21,;which deposits i them on the delivery belts 22,fr0m'v which they are forwarded to and by the .belts lQ; ,It will be understood that similarly, webs led over, the former llj are deposited on the Y belts 22v and forwardedby the belts45=and V 42'; It will also be understood that all or parts of the webs passing over either of the formers maybe deflected to the opposite cuttingdnechanism, f as shown by the dotted lin'e s47 and 48. Thus, all the webs coming from the former l5 may follow the course of the dotted name,- and become associated with webs coming. from the former l5,

- in which. case,the associated product would befdeposited on the delivery belts 22. v

It will be seen thatithe,arrangement'of'the delivery belts is such that the folded papers coming from the "press" are conveyed either on a substantially horiiontal plane or in an it upward direction after theyare placed on the delivery belts by the fan wheels. f It has been fou'nd'that under such conditions, the

papers are forwarded in an orderly manner,- but if the delivery belts are'so arranged that at any place their path is inclined downwardly more than to a slight extent, there is a tendency;for the.papers toslideforward and be-. 'comedisarranged. V if i if The arrangement disolosedherein whereby ;the cuttingmechanism of 'theirear folder is placedon a lower level than the cutting mech-v delivery belts of thejrear delivery are carried ona substantially horizontal plane below the 1 anisni of the front folder, and by which the I front delivery, permits ample space for the operator to'obtain' access to all of the mechal'llSIll and the arrangement whe rebythe shaft '31 is supported in ajdiagonal' positionwith respect'to the frame andwhich permitsboth folding'c'ylinderstobe geared to the same.

' The plates areusuallyplaced on the printing cylinders in such manner, that the print- Y ed papers will be delivered with their headings" facing, upward, as this method facilitates har' dling.v With presses having'their deliveries at loppositesides, when the webs passing over-both formers are associated, and

carried to one of the deliveries, they will be delivered with the headings facing upward, clout, if the webs are carried tothe other delivery, they-will, bedelivered with the headings 'facing downward". 'f B-yK-arranging the folder sothat bothdeliveries are'carri'ed to the same side of; the machine,'the"papers are delivered in the same manner when-using either folderl' It willthus-be understood 'that with the arrangement of deliveries herein'disclosed ,sh'ould any trouble develop with one of the deliveries whenmaking an assofciated run, the lead of th'e'webs can quic'klybe "changed to the other delivery-and still deliver the papers'facin'gthe same Way.
